The various systems meet different needs for each application, for a precise balance between ergonomics and safety. ERGONOMICS Advantages: • The sleeve locks manually, only when desired by the user • Can be operated with one hand Disadvantages: • The time it takes to lock the sleeve SAFETY Advantages: • Reliability in dirty or harsh …
Multipoint Anchors Building an anchor system requires much practice and experience. In the end, simplicity and complexity are competency issues. Competency takes time to build and this doesn’t come without an investment of focus and purpose. Building an anchor system requires much practice and experience. When dealing with structures, chose anchor points that are part …
Building Anchors with Spring Loaded Cams Pull Test Using Metolius Camming Units So we did some back yard testing and while what we found wasn’t particularly astonishing, it was never the less, very interesting. We purposely used some marginal placements with our Metolius camming units. Some more marginal than others. We found a range from …

Excerpt from Anchor Considerations in Rope Rigging Systems Vol. 2 Segment 2 What is a bombproof anchor and what are some methods of rigging anchors? Bombproof anchors can hold it all… but does this principle apply in high directional anchors such as tripods, “A” frames, and gin poles? Questions of this nature are addressed in …

To understand rigging is to understand at least some aspects of trigonometry and vector physics. The knowledge of angles, components, and resultants is synonymous with quality rope rigging. To study vectors is to study the physical qualities of force that has both direction and magnitude. There are two important distinctions we make in quantifying attributes …
Obviously anchoring as a concept is a huge topic. The variations in any given anchoring course can range wildly depending on the vision, scope, knowledge and imagination a give team or person has. Here is what a typical anchoring course would look like. I have rounded them out to 10 topics. Anchor Points Selection and …
So in this installment of Litter Hauling Techniques Using Dual Capacity or Twin Tension Rope Systems Part 2, I would like to jump into anchor and anchor systems used in a few of the systems we set up here this week. Neverland has three upper platforms or stages (as we call them) and the lower Ground …

Now we’re down at the bottom end. As I said at the top, we’ve got our red track line and we’ve got our blue skate block. The attachments here, we’ve got a pulley on the track line. Also on the track line we have a mobile fall arrester, a Petzl ASAP. That means worst case, …

All right, this is the rescue scenario we’re doing right now is called a twin-tension skate block. We have a victim up top, once again, he is a compliant climber. He’s either fallen on his fall arrest device or sitting in his work positioning device, unable to get out of it, and he’s unable to …

Let’s continue with our pulley discussion. We have here a confined space rig, what I like to call it. It’s unique in that we have a tripod, and anybody who’s been around these things know they’re susceptible to tipping over, so it’s important, if you’re going to do something like this, that you have equal forces …
